A lot can be said in a picture, although nothing tells more about a man than what and how he writes.

For the OP; more hypothetical: He could also have been part of a social group where school wasn't a norm or the resources weren't there to pay for school, thus hindering his writing knowledge but allowing for highly adept social skills.

It goes hand in hand. When you have an appealing profile picture, it makes you want to check it out. Likewise, when guys actually take the time to write a bio about themselves, it determines whether or not you actually want to get to know the guy.

There are lots of fuckups with pretty pictures on the internet. When the guy with not pix puts his thoughts and goals into print, then you have an idea of what's going on in his brain, and you can gauge how he will react at the coffee shop meeting if he turns out to be a troll.
